Ultrasonic Flow Measurement - 2D

Model Description

A 2D model of a pipe with a parabolic flow profile in Y direction across the radius of the pipe. With the flow velocity set in positive X direction, the model can be used to evaluate the effect of flow on the receive signal and severity of beam deflection.

Basic Model Schematic

Important: This is not a CFD analysis. A flow field is loaded in the background and its influence on the acoustic wave is studied.

Parametric Variables

The model allows the following design variables to be adjusted to control design metrics such as maximum flow velocity:
